Chitimacha tribal police

Authorities have released the names of the Chitimacha tribal police officer who was killed and the two sheriff's deputies who were wounded Saturday in shootings near a south Louisiana casino.

The slain officer, Sgt. Rick Riggenbach, was a four-year veteran of the tribal police department who also served 10 years as a St. Mary Parish sheriff's deputy. At a press briefing Monday, a Louisiana State Police spokesman called Riggenbach a hero whose actions prevented other people from being hurt.
